THOMAS CRANE, OF FORT'ATKINSON, WVISOONSIN.

IMPROVED SUGAR-CANE PRESS.

Specification forming part of Letters Patent N0. 2 1,376, dated June 14,1859.

170 ct whom it may concern.-

Be it known that I, THOMAS CRANE, of Fort Atkinson, in the county ofJefferson and State of WVisconsin, have invented a new and ImprovedMachine for Expressing the Juice from Sugar-Cane and other VegetableSubstances, and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, which form a part of this specification;

Figure l is a top view of the above-mentioned machine; Fig. 2, a sideelevation of the same; Fig. 3, a section in the line 00 x of Fig. 1; andFig. 4, a section in the line yy of Fig. 1.

Similar letters indicate like parts in each of the drawings.

The frame of my improved machine for expressing the juice fromsugarcane, 85c. may be composed of the two long beams D E,the paralleltransverse beams J J, the jointed beam F, and the other minor partswhich are combined with said beams in the manner represented in thedrawings; or the said frame may be constructed in any other mannerdeemed preferable,by the builder. Such a shape should be given to theaforesaid frame that it will rest safely upon three supports, viz., thelarge wheel A, the small wheel I, and pivot-post K. The machinery uponthe said frame should be so located as to cause the greatest portion ofits weight to rest upon the large wheel A. Two

slotted uprights, I) b, which are connected to each other by means ofbed-pieces that rest. upon the transverse beams J J, carry the bearbeams D E may be covered with thin planks or slats for the reception ofthe cane-stalk and the operator who is to feed in the same between thesaid rollers when the machine is in motion; or a platform, G, may beplaced upon the said beams for the operator to stand upon, andthecane-stalks may be supported by the crosspieces h h, the rail f, whichis secured to the inner ends of said cross-pieces, and the uprights 9 gfrom the opposite ends of said crosspieces.

The journals of the small bearing-wheel I are received into apertures ina pair of lugs which descend from the oblique beam H, which is securedto the main beams D E near the outer ends of the same, or the bearingsof said wheel may be connected with either of the beamsD E in anysuitable manner.

A vessel, a, is suspended to the parallel beams J J, which is of such asize and shape that it will catch all the juice that is eX- pressed bythe rollers BO from any substance that may be passed between them. Atube, 2', which is secured to the under side of the beam F, and whichopens into the vessel a, conducts the fluid contents of said vessel tothe annular vessel j, which incloses the body of the pivotpost K, andfrom this annular vessel 9 the spout 7c discharge the said fluid into areceiving-vat by means of any suitable conductor.

The perforated plate d, which is jointed to the beam J immediately infront of the roller '13, has a sharp upper edge which bears obliquelyagainst the periphery of said roller and prevents the accumulation ofany trashy matter upon the same. The said plate d also serves to conductthe crushed cane-stalks, as they pass through the pressure-rollers, intothe receptacle Lwhich is suspended to the transverse beam J, and totransverse beam m, which is connected to the front ends of the beams Dand E. The handle 0, which rises from one end of the plated, enables thesaid plate to be moved outwardly or inwardly, and by means of suitableweights suspended to the end of said lever the edge of said plate can bemade to bear with any desired degree of force against the periphery ofthe roller B.

The pivot-post Kmay be secured to the center of the cross-arms a n, andthe said arms may be secured in any desired position by means of pins orstakes, or the said pivotpost may be planted in the earth or secured ina fixed positions in any other manner..

The clevis p, to which the power is applied for operating the machine, Igenerally combine with the front end of the beam D, and the outer end ofthe beam F, Igenerally combine with the pivot-post K; but thisarrangement may be varied at the pleasure of the builder.

The respective operating parts of the machine may be so arranged andcombined with the frame of the same that either of its three projectionsmay be combined with the pivotpost.

Having thus fully described my improved machine for expressing the juicefrom canestalks, 850., I would observe thatI do not separately claim tobe the inventor of the pressure-rollers, nor do I claim to be theinventor of the arrangement of the frame by which it may be turned upona centralpivot-post; but

What I do claim, and desire to secure by Letters Patent, is-

The combination of the pressure-rollers B G, with the main bearing-wheelA, of a frame which is so proportioned and supported that it can berotated arounda pivot-post; but this I only claim when a fluid-receivingvessel, a,
